I use CC2 so it may be different on CC3, but try fractalizing your shapes a little more. I usually keep clicking that line until I can't tell it's changing anymore.

Other than that, this is looking good! Have some rep for your first map

What you do with it next is write down all of the things that you want to do better with it then go and make a new map and work on those things. You have a fine map and, other than the landmass shapes, I think it's pretty good. You certainly have the basics down as well as some more advanced techniques so you're ready for bigger and better things. Well done.
